Detailed explanation of how to correctly configure the PHP development environment
Before developing the PHP language, the development environment needs to be properly configured so that our program can run perfectly. So, how to correctly configure the PHP development environment? This article will introduce the download, installation and configuration of apache, mysql, and php, and describe the establishment of development environments in windows and linux environments respectively.

1. Download apache, mysql and php

1. Download apache

The Apache server can download the Windows Apache installation program through the official mirror address, but it is all in English, and the download speed is too slow. I suggest that you go to Huajun, Sky or Zhongguancun to download the latest version of the installation program, which is very fast.

2. Mysql download

The official website of mysql is http://www.mysql.com. You can download the latest version of mysql. Again, it is recommended that you go to Huajun, Sky or Zhongguancun to download.

3. PHP download

The official website of php is http://www.php.net. The latest version can be downloaded.

2. Configure the php development environment under windows

1. The installation of apache, mysql and php is just like installing other software in Windows. It is recommended to install the apache and php software in the d drive directory and the mysql software in the c drive. In this way, there is no need to make any settings, and mysql will be installed. Can start running smoothly.

2. Configure the development environment

In order to allow windows to execute php, further work needs to be done. Follow the following steps to set up the environment:

1) In the php installation directory, find the file php5ts.dll and copy it to the system32 directory on the c drive.

2) In the PHP installation directory, find the file libmysql.dll and copy it to the system32 directory on the c drive.

3) In the php installation directory, find the file php.ini and copy it to c:windows. This file is the basic file for configuring PHP. For example, to set the server root directory configuration, use a text editor to open the php.ini file and find "doc_root=". Because I installed apache in the root directory of drive D by default, modify this configuration. The value of the item is: doc_root=d:apache2htdocs

Tip: Users can modify the value of this configuration item according to the path where they installed apache.

4) Find "extension_dir ="./"" in php.ini. This configuration item is used to load the php extension module. Modify the configuration item as follows: extension_dir = d:phpext, (you need to install it according to your own installation Directory to modify the loading location of php).

5) Find ";extension=php_mysql.dll" in php.ini and remove the semicolon in front of this item to make this item effective. This configuration item is used to enable php to support mysql. The semicolon here serves as a comment. After modifying the php configuration file php.ini, save and exit the file.

　6) Configure apache. Go to the conf directory under the apache installation directory and open the apache configuration file http.conf with a text editor. Find dynamic shared object (dos) support in this file, and add the following configuration item at the end of the loadmodule line: loadmodule php5_module d:/php/php5apache2.dll (you need to modify the loading location of php according to your own installation directory). This item is to load the php module php5apache2.dll through apache, that is, php runs as a module of apache.

7) In order for apache to support files with the .php suffix, find the addtype item in http.conf and add the following configuration item at the end: addtype application/x-httpd-php.php. Find directoryindex and add index.php at the end. In order to support Chinese, find adddefaultcharset iso-8859-1 and change it to adddefaultcharset gb2312. Save http.conf after modification. That is to complete the basic configuration of apache.

Note: It is strongly recommended that when modifying the apache configuration file http.conf, you must abide by the principle of modifying a little and testing a little, that is, after each modification and saving http.conf, you must restart apache. If apache starts normally , then you can make subsequent modifications. Otherwise, it means that this modification is wrong, so check it carefully and modify it again.

3. Configure the PHP development environment under Linux

1. Installation of mysql

Download the mysql installation file mysql-server-4.0.20-0.i386.rpm from the mysql official website, and execute the following command to complete the installation of mysql.

rpm -ivh mysql-server-4.0.20-0.i386.rpm

Without setting a mysql password, run the following command to test whether mysql is installed successfully.

mysql -u root

When words similar to welcome to the mysql mointor. commands end with;or g appear, the installation is successful.

2. Installation of apache

Download the unix version of the compressed package from the official website of apache. Take httpd-2.0.52.tar.gz as an example. Assume that the resource package is placed under /usr/local/src. Enter this directory and decompress it. The command is as follows:

cd /usr/local/src

tar -zxvf httpd-2.0.52.tar.gz

After decompression, enter the directory httpd-2.0.52 and execute the following command:

　./configure --prefix=/usr/local/apache2 --enable--module=so

Where --prefix=/usr/local/apache2 is used to specify the installation directory of apache. Next, compile and execute the following commands to complete the installation.

make

mae install

3. Configure the installation of PHP development environment

1) Download the compressed package of php5.1.4.tar.gz from the php official website and decompress the file package. The command is as follows:

tar -zxf php5.1.4.tar.gz

2) Go to the decompressed directory and execute the following commands to complete the PHP installation directory and other related configurations:

　./configure --prefix=/usr/local/php -with-mysql=/var/lib/mysql

3) Then compile php, the command is as follows:

make

make install

4) Copy the file in the current directory to the lib directory of the php large installation directory, and rename it to php.ini. The command is as follows:

　cp php.ini-dist /usr/local/php/lib/php.ini

5) After the above configuration of the PHP development environment is installed, refer to the configuration content under Windows for relevant configurations. The configuration items and configuration methods are similar.
